Ilhis invention relates to :fruit juice exA y2lb bevused in combination with-the extractor herein shown and described.

'lhe main object o the invention is to produce an' ecient :fruit juice extractor driven by a motor and gearing, and provided with a support, which may be used` interchangeably in either the foodl mixer or the extractor. j

Another object is to provide means for quickly and eiiiciently coupling the juice 2@ extractor. mechanism to the motor drive shaft.

Another object is to produce a juice ex- 'tractor adapted for operative connectlon with an existing type of food mixer motor 25 and gearing without requiring' alteration of the said motor -and gearing.`

Among the advantages oi athe `present invention are simplicity of construction, economy of production and eiiicency for its 39 intended purpose. Y

Fig. 9 is a bottom view of part oi the bowl.

Fig. 10 is a side elevation of the bottom of the bowl. '65 ln Fig. 2, the motor 10 which is used interchangeably to drive a food mixer and a fruit juice extractor is shown resting on a supportlL An agitator unit 12 is operatively connected with the motor and depends therefrom for mixing foods. ln Figs. 1 and 3. the .same motor is shown in inverted position, as it appears ywhen functioning to2 drive the fruit juice extractor.

The motor 1() is provided with a gear 75' casing 13-rigidly secured to the motor casing.` 14 Aindicates one of two food mixer' rotatable agitator rods, 15 is the lframe work of the agitator unit and 16 indicatesa liand Hactuated screw bolt or plunger which Vengages part of the frame work of the agitator unit and retains it in the gear casing. The motor handle is'lindicated at 17.` As a food mixer this device is positioned on the support 11 and isadjustably held'thereon by 85 means .of an aperturedange plate 18 ixed l f tothe motor 10, engaged by the pin 18 on the motorV support 11.

When it isdes'ire'd to use the motor- 10 as a means for driving/the fruit juice extractor, the agitator unit 12 is removed by unscrewing the bolt 16 and then the motor-is turned upside down, relatively to thel support 11 as shown in Figsrl and 3.

The horizontal motor'shaft 19 carries a 9.5. worm-.gear on its forwardend which meshes with worm wheels 20'ixed on the. vertically disposed driven shafts 21 mountcdin bearings 22. The shafts 21 terminate'in square ends 23 which depend-'from thegear casing 10 13 and engage the holldw endfi 14 of the agitator rods 14 of the unit 12 .when the motor is in the position shown in Fig. 2.` When the motor is used in connection with the fruit juice extractor mechanism, the square ends 23 protrude `upwardly and one of them engages part of the extractor mechanism as will be hereinafter described. Preferably the shaft 21 which drives the extractor shaft is provided with a thrust bearing 21 consisting of a 'hardened steel disc against which the ball thrust runs with decreased frictional Contact, the same being located in the socketof the gear'casing 13. The block portion 24 of the gear casing is bored vertically as indicated at 25 in Fig. 3 for receiving the non-rotatable square center support of the food mixer agitator unit (not visible in Fig. 2) or a square rod Qn the extractor apron.

From, this it will beunderstood that the food mixer motor and gear mechanism are made attachable to the extractor mechanism by simply loosening the part 16 and removing -the agitator unit l2.

Referring now more particularly to Figs. 1, 3 and 5 t'o 8, inclusive, the extractor apron comprises a flat plate 26 provided with a depending marginal flange 27 inturned at 28 to engage the motor rest arms 29 of the support 11. On its under side the apron 26 is reinforced with` a plate 30 having a depending tongue 31 which contacts with the cross bar 32 between the 'arms 29 of the support l1 and prevents the apron from vslipping forwardly relatively to said support.

Depending from the plate 30 on the underside of the apron 26 is a member 33 terminating in a square rod 34 which is adapted to enter the bore 25-of the gear casin 131and to be engaged by the bolt 16 for holding the motor in proper operative position relatively to the extractor apron, as shown Figs. l and 3.

Extending through the apron 26 and plate 30, above and below-the same, is a'. reamer drive shaft 35 mounted in a floating bearing housing 36.1ocated on the apron by a. pin 37 and permanently positioned by upsetting the bottom of the bearing housing over the apron 26. Within the bearing housing 36 is a self-aligning bearing'38 and a spring 39 surrounding the bearing 38. The bearing 38 co-operates with the comple- Inentally curved inner walls of the housing 36 to provide a iioating bearing for the shaft 35. On its lower end the shaft 35 is provided with a cup-shaped member 40 internally shaped to receive the square end 23 of one of the shafts 21 of the motor gearing. The spring 39 normally holds the bearing 38 in 'its seat but permits movement ofthe bearing relatively to the housing 36 for the purpose of aligningthe shaft35 with one of the shafts 21 ofthe motor. Above the housing,`

36 the shaft 35 is provided with a screw threaded end 42 forcarrying the reamer-engaging head 41.

The juice receiving bowl -43 is removably held on the apron 26 by`mechanism on the apron engaging flanges on the bowl. bowl base 44 is formed with twoV tapered flanges 45, that is, the upper surfaces orv shoulders of the flanges are inclined in the same direction. The bowl is preferably made of glass and the parts are so arrangedv when assembled that the juice does not contact with the metallic parts of the extractor. The bowl attaching means include a locating plate 46 fixed to the bearing housing 36, said plate having oppositely disposed projections 47 adapted to lit between the ends of the flanges 45 on the bowl 43, and

a clamping device cousistingfof a plate 48 having clamp arms 49 and an operating lever 50. rlhe clamping Cdevice is located be.

tween the locating .plate 46 and apron 26. The bowl 43 may be positioned on the plate,

Yfullest extent and securely hold the bowl 43 j in position on the apron.

0n its inner surface the bowl is preferably provided with an integral inverted cupshaped member 52, best shown in Fig. 3, which is centrally apertured to t over the shaft 35-41, and to cover the bearing housg -ing 36 when the bowl is in position. The

aperture in the cup-shaped member is suiciently large to permit the bowl to be positioned on the locating plate 36 by merely removing the reamer 53 from the head 41.'

The bo is provided with a spout 54,- which when thebowl is properly positioned as intended will deliver the extracted juices to a container without soiling the motor or, other ,parts of the mechanism.

Changes may be made/in details of construction without departingfrom the scope of my invention ,and I do not intend Vto be' limited to the exact -form shown and de- I vscribed except'l as set forth inthe appended claims. d
